Patient portals can have positive consequences in the empowerment of people with depression by raising awareness about their condition. Patient portals are important yet challenging technologies in the field of mental health care. We conducted a scoping review aiming to investigate some important characteristics and features of the mental health websites and related patient portal services for the target audience including people with depression. For this purpose, two reviewers independently entered the keywords in the popular search engines including Google, Yahoo, and Bing in April 2019, in order to find mental health websites that provide patient portal service targeting depression. Examination of the inclusion and exclusion criteria led finally to the selection of 31 websites. We found out that some features of patient portals including the online questionnaires, messaging between the patient and the healthcare provider, and medication refill were more consistent with the areas on which the mental healthcare providers focus, and thus can be effective in improving the progression of these areas. It is essential for patient portal providers to put more focus on expressing the patient portal’s features and objectives on their websites. Besides, it is also necessary to conduct further research to investigate the obstacles and facilitators of the interactive features of the patient portals in the field of mental health care, particularly depression.
